Simplify each expression and identify the units you and two friends all have the same real meal for lunch.Each meal costs c doll

ars plus a tax of 6% of the cost and a tip of 20% of the cost. You use a $10 gift certificate. You can represent the total cost with the expression 3c+(0.06+0.20)(3c)-10

T.C = <span>3c+(0.06+0.20)(3c)-10
3c = cost of 3 meals
3c(0.06 + 0.20) = tax and tip expenses
10 = value of gift certificate
T.C = 3c + 0.26*3c - 10 = 3.78c - 10.</span>

Please help I need to know the answer
Kazeer [188]
Answer:

Original price: 51$
Discount percentage: 40%

-----------

Details
Discount = Original Price x Discount %/100
Discount = 51 × 40/100
Discount = 51 x 0.4
You save = $20.40

Final Price = Original Price - Discount
Final Price = 51 - 20.4
Final Price = $30.60

there you go, coupon A is 20.40$ Dollars less than the price of coupon B, your welcome :)) i wish u best of luck in the exam:)

also, please mark me as brainliest, it would really help me out, thanks :))

Solve number 8 please
beks73 [17]

Answer:

see explanation

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k )² = r²

where (h, k ) are the coordinates of the centre and r is the radius

given

x² + y² - 8x + 8y + 23 = 0

collect the x and y terms together and subtract 23 from both sides

x² - 8x + y² + 8y = - 23

using the method of completing the square

add ( half the coefficient of the x / y terms )² to both sides

x² + 2(- 4)x + 16 + y² + 2(4)y + 16 = - 23 + 16 + 16

(x - 4)² + (y + 4)² = 9 ← in standard form

with centre = (4, - 4 ) and r = \sqrt{9} = 3

this is shown in graph b

Find the image of (-7,-3) reflected across the x-axis
Korvikt [17]
IF USING GEOMETRY...

x-axis = (x, -y)

Because the x does not have a negative sign the number DOES NOT change to its opposite form, but because the y has a negative sign the number DOES changes to its opposite form (from negative number to positive.)

So... if we use the formula of x-axis, which is (x, -y), the coordinates (-7,-3) would change to (-7, 3)

ANSWER (-7, 3)

Please help me out please please !!!!!
Sauron [17]

The surface area of a sphere is given by

S = 4\pi r^2

We deduce

r = \sqrt{\dfrac{S}{4\pi}}

So, in your case, the radius is

r = \sqrt{\dfrac{100\pi}{4\pi}}=\sqrt{25}=5

The volume of a sphere is given by

V=\dfrac{4}{3}\pi r^3

So, we have

V = \dfrac{4}{3} \pi 5^3 = \dfrac{500}{3}\pi
